Problems solved by technology

However, due to the unstable characteristics of thermoelectric output, it brings obstacles to the stability regulation of building energy saving, which limits the promotion of this technology.

In order to solve the problem of unstable system output, the predecessors proposed a solar system coupled with energy storage equipment, and the use of energy storage equipment can greatly reduce the instability of the solar heat pump system, but because the energy storage equipment needs to provide an additional installation location, in Promotion in urban areas with scarce land resources lacks practicality and economy

In addition, PV / T panels using water and air as heat exchange medium have been promoted in the market due to their low cost and simple structure, but due to their poor heat exchange effect and weak heat migration ability, the overall efficiency is not as good as that of refrigerants. Medium direct expansion PV / T panels
